The 3NB 500 reciprocation pump with three single functional cylinders chooses optimum parameters, increases the stroke properly, and reasonably reduces the number of punchings to improve the the pump suction property and to prolong the life of quick-wear parts. This pump has been widely used in oil fields, other industrial and mining enterprises, well drilling, well repair, liquid medium transport in long distances, multi-well water flooding pump station, polymer injection and other operations. It mainly adapts to the 50-90 drilling rig.

The 3NB600 reciprocation pump with three single functional cylinders chooses optimum parameters, increases the stroke properly, and reasonably reduces the number of punchings to improve the the pump suction property and to prolong the life of quick-wear parts. This pump has been widely used in oil fields, other industrial and mining enterprises, well drilling, well repair, liquid medium transport in long distances, multi-well water flooding pump station, polymer injection and other operations. It mainly adapts to the 50-90 drilling rig.

The F800 reciprocation pump with three single functional cylinders chooses optimum parameters, increases the stroke properly, and reasonably reduces the number of punchings to improve the the pump suction property and to prolong the life of quick-wear parts.
